Description
Technical field
The present invention relates to the installation methods of a kind of optical cable and the connection structure of construction surface, for bridge, tunnel, subway and other places
Side.
Background technique
In recent years, the development of subway, bridge, Tunnel Engineering construction presentation blowout, the monitoring structural health conditions of engineering are also got over
More to attract people's attention.Compared with traditional sensing mode, Fibre Optical Sensor have high sensitivity, anti-electromagnetic interference capability it is strong,
Signal fidelity is good, the advantages such as adaptable, and can carry out real-time monitoring to the structural health of engineering.Based on Fibre Optical Sensor skill
The monitoring structural health conditions scheme of art has become mainstream, this just needs to be laid with optical cable in engineering, is related to optical cable therewith and fixes
The problem of.
The relaxation degree of both ends optical cable is vital behind the fixation position of optical cable and fixation.The optical cable of the prior art is solid
Determine device to need to be assembled at the construction field (site) mostly, then install, there are also optical cable fixing devices to need at the construction field (site) first to portion
Part disassembly, just can be carried out installation, this causes long using the construction time needed for these optical cable fixing devices, is unable to satisfy rapid construction
The requirement of engineering.And after installation is complete, if occur both ends optical cable on one side relax, while situation about tighting, after can only dismantling
It is installed again, not only extends the construction time, also add difficulty of construction.Therefore, one kind is invented to fix convenient for optical cable, and
There can be important invention meaning to the device that the elastic state of both ends optical cable is adjusted.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings and to provide the installation sides of a kind of optical cable and the connection structure of construction surface
Method can be assembled first, and optical cable, which is directly then caught in the device, at the construction field (site) can be completed installation, and can adjust both ends
Optical cable it is elastic.
The object of the present invention is achieved like this:
A kind of installation method of the connection structure of optical cable and construction surface, which passes through multiple optical cable fixing devices will
Optical cable is fixed in construction surface, which passes through each optical cable fixing device, is then connect by optical cable fixing device with construction surface
Fixed, the optical cable fixing device includes bolt, fixinig plate, nut, nut, lock pin and iron plate ring, and the bolt is in open tubular column
Shape, bolt are lockked by the external iron plate ring being nested with, to be fixed on construction surface, nut is torqued-up to iron plate ring from the both ends of bolt
Place is fixed, and the fixinig plate is for fixing optical cable, and fixinig plate is placed in bolt, and the fixinig plate has two panels, wherein one
Piece fixinig plate inside edge is fluted, and corresponding positions are equipped with protrusion, the two panels fixinig plate outer side center on the inside of another fixinig plate
There is screw hole, there is one section of strip projected parts in centre, and strip projected parts both ends to fixinig plate edge are domatic slot, height of the domatic slot lower than protrusion
Degree, the nut and lock pin combined by card slot, and distribution is fixed on bolt both ends, and the lock pin is in pincer, under lock pin
Portion is two pincers feet, and lock pin is used for the fixinig plate in fixing bolt, spiro cap at bolt both ends, the bolt, nut, nut,
